激光表面工艺 ( LSE)是采用大功率激光束熔化陶瓷粉母体及基体薄层形成激光熔区 ,并通过高速率冷却破坏固熔体平衡相图产生亚稳态相 ,从而获得常规工艺无法达到的具有不同微观结构的优异性能。LSE涂层与基体间是冶金结合 ,结合牢固紧密 ,并可通过调整工艺参数及母体成分获得所 Laser surface technology (LSE) is the use of high-power laser beam melting ceramic powder matrix and thin layer of the substrate to form a laser melting zone, and by high-rate cooling destroy the equilibrium phase diagram of solid solution to produce metastable phase, so as to obtain the conventional process can not be achieved Excellent performance with different microstructures. LSE coating and the substrate is a combination of metallurgical, with strong and tight, and can be adjusted by the process parameters and the parent component
